Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
"Men's Daily Muti-Herbal" (typo: "Muti" for "Multi") is a proprietary blend from a small herbalist typically combining saw palmetto, pygeum, nettle root, tribulus, maca, ashwagandha, and various other men's-health botanicals with no per-active mg or standardization percentages. Each active has distinct evidence (saw palmetto 320mg standardized for BPH per Wilt 1998, though negative in larger trials; ashwagandha KSM-66 for stress-testosterone) but blending them at unstated doses destroys the ability to evaluate the product against any of those evidence bases. Product-title typo ("Muti" instead of "Multi") is a QA signal — brands with real GMP oversight catch label typos. Auto-failed under proprietary_blend_hides_dose.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

The Vyvata score measures product integrity against a published rubric, not customer sentiment. Vyvata does not aggregate, republish, or license third-party reviews — the links below open search pages on their respective platforms.
Every VSF-related metafield surfaced verbatim. Nothing hidden. If you spot data that looks wrong, let us know.
Every score is set from the published rubric, audit-logged, and rescored whenever new evidence emerges (published trials, updated labels, third-party testing releases). Every vendor is scored on the same criteria — no pay-to-play. See our editorial-independence disclosure for the full policy, including brands with an editorial relationship to this site.
